PICKER-STICK-OPERATING MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 455,563, dated July '7, 1891. Application filed June 24,1890. Serial No. 356,518. (No model.)

To all whom it may concern: 7

lowing is a specification.

This invention relates to improvements in picker-stick-operating mechanism for looms; and the object of my invention is to provide a new and improved picker-stick-operating mechanism for looms which is simple in construction, can readily be adjusted, and which is provided with a filling check-spring.

In the accompanying drawings, Figure 1 is a longitudinal elevation of my improved picker-stick-operating mechanism for looms, showing the manner in which it is applied on a loom, parts being in section; and Fig. 2 is a transverse sectional view on the line; 2 of Fig. 1..

Similar letters of reference indicate corresponding parts.

The picker-stick A is pivoted at A, and is adapted to swing in the recess 0 in the end part of the lay-beam B, at the ends of which recess 0 the back bumper or cushion B and the forward bumper or cushion B are fixed. To the lower end of the picker-stick A a clip D is fastened by a bolt D passing through the lower part of the picker-stick, which bolt also, strengthens the picker-stick and prevents the splitting of the same. To the clip D one end of a rod E is hinged, the other end of which is clamped on one end of a rod F, provided at the opposite end with a ball G, working in a socket of the clip H, which clip is fastened to one end of a rod or bar J guided to reciprocate lengthwise in the standards K on a suitable base L. A filling check-spring M, which is helical in shape, surrounds the .rod J between the clip H and one of the guides K, and a like but longer helical spring N surrounds the rod J between one guide K and the adjustable collar 0 on said rod, which collar can be adjusted by means of a binding-screw 0 The right-hand end of the rodJ projects beyond the right-hand guide K, and on said right-hand end of the rodJ a collar R is held by a screw R. The rodsE and F are clamped together by two rings P, having clampingguide K,

screws Q. The ball-and-socket connection between the rods F and J permits the rods E and F to move freely with the picker-stick in different directions without affecting the rod J or causing the same to bind von its guide. The spring IV is secured on 'the top of one and is provided atits free end with an upwardly-bent arm IV, and adjacent to said arm WV with a recess or bend V adapted to engage the topof the guide K.

The operation is as follows: By means of the arm a on the rock-shaftb the picker-stick is swung in the direction of the arrow 00 to throw the shuttle, whereby the spring N is compressed, and when the picker stick has thrown the shuttle the spring N throws the picker-stick back in the inverse direction of the arrow x.

To prevent the undue hammering noise of the picker-stick striking against the bumpers B B the device is adjusted in the following manner: The screws Q Q in the rings P Pare loosened and the picker-stick is adjusted so that its upper end is a certain distance, more or loss, from the bumper B and then the screws Q Q are tightened. When the pickerstick is moved in the inverse direction of the arrow 00 by the expanding spring N the fillin g check-sprin g M is thereby compressed and the force of the picker-stick is diminished by the compression of the spring M to such an extent thatitcannotstrikeagainstthebumperB with sufficient force to make any undue noise.

By means of therings P P and screws Q Q the picker-stick can be adjusted for any desired position and for any kind of filling used in a loom. In case box-Work is to be made on the loom the spring WV comes into play, as it looks the picker-stick A in the position of rest in the manner shown in Fig. 1 during the time that the boxes are being shifted; When the picker-stick is swung in the direction of the arrow 41: the spring WV is unlocked automatically and its recess 7 is withdrawn from the guide K. When the picker-stick moves in the inverse direction of the arrow m the beveled end W of the spring WV strikes against the top of the guide K and slides over the same to permit the recessed part of the spring IV to engage said standard. The collar R on the end of the rod J prevents the loom-fixer from adjusting the spring N in such a manner as to act too forcibly on the picker-stick, as it prevents the spring from giving the stick too much throw. The tension of the spring N can easily be adjusted by means of the collar 0 on the rod J.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination, with a reciprocating rod, of two guides in which the rod can reciprocate, a helical spring surrounding said rod between one guide and a collar on said rod, an additional helical spring surrounding said rod between the other side of the above-mentioned guide and a clip on the end of the rod, and an extensible rod connecting the clip on the reciprocating rod with the picker-stick, substantially as set forth.

2. The combination, with a picker-stick, of a clip bolted to the lower end of the same, an extensible rod fixed to said clip, a rod reciprocating in suitable guides,a spring surrounding said reciprocating rod, and an adjustable collar on the reciprocating rod,

against which collar one end of the spring rests, substantially as set forth.

3. The combination, with the picker-stick A, of the reciprocating rod J ,the guide K for the same, an extensible rod connecting the picker-stick with the rod J, the clip H on the end of the rod J, the helical spring M, surrounding the rod J between the clip H and guide K, the helical spring N, surrounding the rod J, and the adjustable collarO on said rod, substantially as set forth.

4. The combination, with the picker-stick A, of the reciprocating rod J, surrounded by the springs M and N, fixed guides for said rod, an extensiblerod connecting the pickerstick with the rod J, and the lock-spring WV, secured 011 one end of the reciprocating rod, adapted to engage one of the fixed guides, substantially as set forth.

5. The combination,with a picker-stick, a reciprocating spring actuated rod, means for connecting said rod with the picker-stick, and a lock-spring on the end of said rod, which look is adapted to engage a fixed object, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
